Embodiment 1

Reference is made to FIG. 1 to FIG. 4, the present invention discloses astorage bed including a bed body 1 provided with a storage cavity, a bedboard frame 2 covering the bed body 1, parallelogram lifting mechanisms3 symmetrically arranged on two sides of the bed board frame 2, anddriving devices 4, wherein the parallelogram lifting mechanisms 3 areconnected to inner side walls of the storage cavity and the bed boardframe 2, and the driving devices 4 drive the parallelogram liftingmechanisms 3 to push the bed board frame 2 to be horizontally liftedtowards a footboard direction of the bed body.

Therefore, the parallelogram lifting mechanisms 3 are utilized to pushthe bed board frame 2 to be horizontally lifted towards the footboarddirection of the bed body 1, so that the bed board frame 2 is preventedfrom coming into collision against a headboard in a lifting process; itis unnecessary to take down bedclothes when articles are stored ortaken, so that the storage bed is convenient to use; and meanwhile,after the bed board frame 2 is horizontally lifted, a larger operationspace for storing or taking the articles can be ensured.

In this embodiment, each of the parallelogram lifting mechanisms 3includes a fixed board 31, a supporting member 32, a first connectingrod 33, and a second connecting rod 34, wherein the fixed board 31 isarranged on the inner side wall of the storage cavity of the bed body 1,the supporting member 32 is arranged on the bed board frame 2, and twoends of both the first connecting rod 33 and the second connecting rod34 are respectively hinged to the fixed board 31 and the supportingmember 32. Therefore, each fixed board 31, the corresponding supportingmember 32, the corresponding first connecting rod 33 and thecorresponding second connecting rod 34 form a parallelfour-connecting-rod structure to achieve the horizontal lifting of thebed board frame 2.

It may be understood that each fixed board 31, the correspondingsupporting member 32, the corresponding first connecting rod 33 and thecorresponding second connecting rod 34 are hinged with one another toform the parallel four-connecting-rod structure, and therefore, thedistance among all hinge points is limited in the parallelfour-connecting-rod structure. Specifically, if each fixed board 31 ishinged with the corresponding first connecting rod 33 by a hinge pointA, each fixed board 31 is hinged with the corresponding secondconnecting rod 34 by a hinge point B, each supporting member 32 ishinged with the corresponding first connecting rod 33 by a hinge pointC, and each supporting member 32 is hinged with the corresponding secondconnecting rod 34 by a hinge point D, a linear distance between thehinge point A and the hinge point B is equal to a linear distancebetween the hinge point C and the hinge point D, and a linear distancebetween the hinge point A and the hinge point C is equal to a lineardistance between the hinge point B and the hinge point D. The relativedistance relationship among all the above-mentioned hinge points is onlyrequired to be met, but specific shapes of the fixed boards 31, thesupporting members 32, the first connecting rods 33 and the secondconnecting rods 34 are not limited.

In this embodiment, each fixed board 31 is provided with supporting legs311 for supporting the ground. Therefore, a force borne by each fixedboard 31 during lifting is not required to be completely transferred tothe bed body 1 and may be partially supported by the correspondingsupporting legs 311, and thus, the phenomenon that the fixed boards 31are loosened or separated from the bed body 1 after being used for along time is avoided. Specifically, three supporting legs 311 areprovided, wherein two of the supporting legs 311 are connected to twoends of the fixed board 31, and another supporting leg is connected to amiddle section of the fixed board 31. Actually, the positions and numberof the supporting legs 311 arranged below the fixed board 31 are notspecifically limited.

Specifically, eachextension rod 331 is connected to the end, hinged with the correspondingfixed board 31, of the corresponding first connecting rod 33, a motorend of each electrically-driven push rod is hinged to the middlesupporting leg 311 of the corresponding fixed board 31, and a telescopicend of each electrically-driven push rod is hinged to a tail end of thecorresponding extension rod 331.

Moreover, ina use process of the storage bed, by energizing the electrically-drivenpush rods, the electrically-driven push rods start to stretch out anddraw back and drive the first connecting rods 33 to rotate so as to pushthe bed board frame 2 to move in a lifting manner, then, the bed boardframe 2 is lifted or drops to reset so as so expose or close the storagecavity of the bed body 1, and it is unnecessary to lift the bed boardframe 2 with a hand, so that the storage bed is convenient to use; andthe electrically-driven push rods are self-locked when beingde-energized, so that the problem of sharp drop or locking incapabilitywhen the bed board frame 2 is opened is avoided, and high safety isachieved.

By using the reinforcing rods332, the strength of the extension rods 331 can be improved, and fatiguecracks and damage on a junction between each extension rod 331 and thecorresponding first connecting rod 33 can be avoided.
